ROSIN-HOLDER.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed May 20, 1914. Serial No. 839,918.

I0 all whom it may concern:

Be it known that we, WILLIAM F. T. MOL- LENHAU'ER and HARLAN E. LEAOI-I, citizens of the United States, residing at Owatonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements. in Rosin-Holders; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide an improved holder for rosin or other resinous substances, such as used on the hair of violin bows and other bows used in playing stringed instruments.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings: Figure l is a plan view of the holder proper with the cover or casing removed; and Fig. 2 is a side elevation of the holder showing the cover or casing applied thereto, the latter being in section.

The holder is preferably constructed from wood, but may be made of any suitable material. It is formed with a base that is preferably cylindrical, and is provided with parallel laterally spaced prongs 2 that are preferably concavo-convex in cross section and formed integral with the said base 1. Between the prongs 2, the base 1 is provided with a raised portion 3 which has the same width as the prongs 2. The construction just noted is important.

The numeral 4 indicates the rosin whichis contained between the prongs 2 and rests upon the raised base portion 3. Preferably, the body of rosin is cast into the space be tween the prongs, while in molten condition. This may be very conveniently accomplished when two boards or plates are placed against the sides of the prongs and against the sides of the raised base portion 3, so as to thereby form a complete mold within the holder. The raised portion 3 is important because it permits the mold boards to be extended below the bottom of the mold and thereby insurestight joints to prevent leak-.

ered with a wax paper, and when they are removed, leave the rosin body of the same width as the said prongs 2 and raised hub 3.

The prongs 2 are preferably made concave at their inner surface, because in this way, the greatest strength with a given amount of material is provided. When the holder is to be used to contain a cake of rosin previously cast, the concavo-convex form of the prongs is necessary in order to keep the rosin from being forced out of the holder in the act of applying the rosin to a how.

The numeral 5 indicates a cylindrical cover or casing which is open at one end and is adapted to be telescoped onto the prongs 2 and against the base 1.

What we claim is:

1. A rosin holder comprising a base, laterally spaced prongs rising from said base, and a raised hub on said base between said prongs, the said prongs and hub being of the same width, and said base projecting laterally beyond said hub.

2. A rosin holder comprising a base and laterally spaced rigid prongs having parallel edges, said base projecting laterally beyond said prongs, combined with a cake of rosin cast between and against said prongs and upon said base.

3. A rosin holder comprising a base, laterally spaced prongs rising from said base, a raised hub on said base between said prongs, the said prongs and hub being of the same width, and said base projecting laterally beyond said hub, and the said prongs having concave inner surfaces for holding a cake of rosin between them.

4. A rosin holder comprising a cylindrical base, laterally spaced concavo-convex prongs projecting from said base, a hub on said base extending between said prongs and having flattened sides, the said base projecting laterally outward beyond said prongs and hub, and a casing adapted to be telescoped over said prongs.

In testimony whereof we aflix our signatures in presence of two witnesses.
